An interesting comparison of geomagnetic activity, starting
three days before the event until the following day. Comparing
the day of the earthquake activity with the previous ones: it is
clear that It does not highlight any abnormal activity. They are
visible PC1 and the background noise at very low frequency,
increases in the evening, as usually happens every day. It is
clear that Kiruna observatory does not received emissions on a
planetary scale, associated with the earthquake, at least on
these frequencies. But let's see what happens in another
important observatory in Finland.

(Finland)
As in Kiruna, no abnormal signal associated with the earthquake.
If you do not know on what day happened the earthquake, looking
at the spectrogram of the various days only, you are not able to
establish any connection between earthquake and radio signals at
these frequencies. And now data coming from our network.
